Knives

When I worked as a mechanic, long before multitools were popular, I carried an old folder handed down from my father. He had broken off the tip of the main blade so I ground it square and smooth and used it as a screwdriver, the edge was still useful for cutting belts and hoses and stripping wire. One of the other blades I kept sharp for scraping gaskets. I've since thought how great it would have been to have a basic multitool back then.
